'.FIREPLACE-GRATE.

Specification of Letters Patent.

Application filed April 9, 1913.

Patented Sept. 2, 1913.

Serial No. 759,857.

To all whom 'it may concern Be it known that I, JENs I. HANSEN, a citizen of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fireplace- Gratos, of which the following is a specification.

This invention relates to grates, and particularly to grates adapted for use in tire places.

The object of the invention is to form a grate improved with respect to the means for dumping the ashes and for confining the body oit' fuel and for admitting air thereto.

In the accompanying drawings-Figure 1 is a top plan view of the grate. Fig. 2 is a front elevation. Fig. 3 is an end elevation. Fig. 11 is a section on the line 1 -1 of Fig. 2. Figs. 5, 6, 7 and S are details of parts of the grate structure.

Referring specifically to the drawings, 10 indicates a substantially rectangular boxlike frame for confining the fuel body. At the front this has a grating formed b v vertical slots l1. The box 'l0 is mounted upon or is continuous with a lower box-like casing 10a which constitutes the ash chamber, and this lower part has at the front a hinged door 12, provided with a sliding damper 13 to control the draft.

The grate bars 111 are located at the bottom of the box 10, above the ash chamber. A pair of these grate bars are used, and they are of the rocking type, each bar having at one end a gear 1G, and provided with trunnions which rest in bearings in the ends oit' the frame. The gears 16 on the two grate bars mesh with each other, and the extended trunnion of one bar is provided with a crank arm 18 operated by a handle rod 19 which may be pulled to turn the grate bars and dump or shake the grate. The front and rear walls of the boX are provided with shields or guides 20, to direct the fuel toward the grate bars, and the lower ends of these shields are toothed to permit the ingers of the grate bars to pass between.

In the lower compartment or ash box 10 are mounted a pair of rotary plates the trunnions of which rest in bearings in the end walls of the box and are provided at one end with gears 1Gn which mesh with each 'other and also with the gears 1G of the grate bars, so that when the grate bars are agitated or rocked the plates 15 are similarly moved.

In use, the device shown will bc set in a [ire place in the ordinary manner, the floor line being indicated at 2l and the lower end of the ash box 10 being preferably connected to an ash chute (not shown) in the cellar, or otherwise. The gears 1G and 1G are inclosed in a easing 17 secured to the outer end of the frame.

The draft is controlled by the damper 13 in the usual manner, and normally the plates 15 close the ash outlet and prevent the tlow of air through the same. Then the grate is dumped the plates 15 are rocked on their pivots to vertical position, and the ashes will then fall through the same and out at the bottom of the ash box. The ordinary droppings of ashes from the grate are caught by the plates 15 and held until the whole contents of the grate are dumped.

I claim:

A tire-place grate comprising a box-like Casing having an upper fuel compartment with a grating at the front, and a lower ash compartment provided with a draft door at the front, a plurality ol rocking grate bars mounted in the casing at the bottom of the fuel eomlmrtment, a plurality of rocking ash plates mounted in the ash eompartnient below the door thereto, and gearing between said grate bars and ash plates, whereby the grate bars and ash plates are all operated simultaneously.

In testimony whereof, I allix my signature in presence of two witnesses.
